Raspberry Pi - Server

[iceflame]

I have successfully installed eqemu in RPi3 with Linux installer.
There are 3 key points to let it run without error.
1 is for RPi, and 2 are for ARM Arch.
1. Enlarge swap memory for compile. Original is 100M, I enlarged to 2G.
2. Fix the code in embperl.cpp for prevent segment fault (ERRSV).
3. Fix float operation by memcpy function for prevent signal SIGBUS, Bus error.
(zone/map.cpp,common/misc_function.h,common/base_packet.h)

I have completed most quests in tutorial zone,
and traveled to some zones to do some newbie quests with bots.

Hate to Rez an old thread but I have been working on a compile myself. Cannot seem to get it up. If I just gave you a RPi online 24/7 - could you help with this? I have a few of them so setting one online isn’t a big deal/dedicating it for eqemu dev.

1. swap file: /etc/dphys-swapfile
https://www.raspberrypi.org/forums/v...ic.php?t=46472
2. ERRSV: embperl.cpp
Modify the code:
if(SvTRUE(ERRSV))
to:
if((count == 0) && (SvTRUE(ERRSV)))
3. memcpy: many files, use memcpy for float
example:
float x;
float y;
float z;
//float x = *(float*)buf;
memcpy(&x,buf,sizeof(float));
buf += sizeof(float);
//float y = *(float*)buf;
memcpy(&y,buf,sizeof(float));
buf += sizeof(float);
//float z = *(float*)buf;
memcpy(&z,buf,sizeof(float));
buf += sizeof(float);

Iceflame,

I was digging around and realized today that you could potentially run an EQ client on RPi 3b+ using ExaGear + WINE.

So RPi uses ARM and EQ needs x86 processor.

ExaGear lets you install x86 on ARM processor with Wine.

Direct quote from their website:
"With Eltechs ExaGear Desktop you can run Intel x86 applications on your ARM-based Mini PC simultaneously with common native ARM applications. You can even run Windows applications on your ARM Mini PC using x86 Wine. ExaGear is a virtual machine that allows you to make your ARM device more flexible, combining programs with different architecture in one system. It is like QEMU but 5 times faster!"

Has anyone done this? If not...could we??

Imagine it...

Step 1) RPi#1 - EQEMU Server
Step 2) RPi#2 - EQ Client
Step 3) ...
Step 4) Profit.

distcc works to compile it too. Still have to increase the swap, but it'll shave quite a bit of time off the compile.

Granted, once it's up it runs terribly, but hey

Hi guys,
Sorry to revive a long dead thread,
but would it be possible for someone to post the binaries compiled for raspberry for the latest Eqemu release ? maybe just the modified files would be enough.
I tried following the suggestions from iceflame to do it myself but i am not a developer so this is out of my reach.

The latest raspberry pi 4 have lots of horsepower so it would be perfect as
a home toy to run eqemu ( max 2 clients ) maybe with an external database ( to avoid burning the sd card ).

Thanks to anyone wiling to help me.

cheers

In the next few weeks, I planned on playing around with this on my 3b+.

[joligario]

Did a successful manual build on my 3b+ today. Haven't confirmed if it runs with no issues yet or not...

One of the reasons I feel this idea hasn't exactly taken off is due to the fact the largest expense to playing on an Everquest Emulator, is the client laptop or computer itself. Because we can setup the emulator on that same device and then run it locally we literally don't need to spend a dime on additional hardware. I currently run my server on a micro PC with a Corei7 processor and 64GB's of Ram and SSD. It's tiny, but it is a bit pricey. The Rasberry Pi argument is all about the hobby of it and seeing if it can be done. I have a couple units in stock, so I may start dabbling in it, but it's important to allow the emulator to run as it does today, or you risk needing to do a lot of development. So the first hurdle is how to run Native Linux on a Rasberry Pi? I know esxi has been setup on a Pi before, and that could simplify things.

Built/ran on 3B+ using fresh arm64 Raspbian Bullseye install last night. Only needed to increase swap size.

[Rikon]

No joy for me on Raspberry 4. Plan to play with it a bit.

[joligario]

Not sure what problems you are having, but recommend limiting cores on build.

My post wasn't helpful. Once I get back home and fire it up, I'll try to capture the issues. I'll also limit cores when building.

[joligario]

You now need a bigger swap - recommend 3GB.
